- to be a full, clear, andcxact description of the same, and which said drawings constitute part of this application, and represent,

Figure 1, a view partly in side elevation and partly in central longitudinal section of one form which an impact-illuminating bullet. constructed in accordance with my invention may assume. Fig. 2, a view in trans verse section on the line a-b of Fig. 1. Fig. 3, a view partly in side elevation and partly in longitudinal section of a modified form which my improved bullet may assume. Fig. 4, a corresponding view showing my invention embodied in a jacketed bullet.

My invention relates to an improvement in that class of bullets charged with a composition fiashing upon the impact of the bullet and thus illuminating the place where it struck for the information of the user of the gun from which it was tired, the object being to produce a superior bullet construct- .ed with particular reference to reliability of operation in the magazine and mechanism of the gun, and to the production at the time of impact, with an exceedingly brilliant illuminatioinof a circular area the ccnterof which is the point of impact. 7

lVith these ends in, view, my invention consists in an impact-illuniinating bullet having certain details of construction which will be hereinafter described and pointed out in the cla ms.

In carrying out" my invention as shown in Figs. 1 and 2, I form a relatively large concentric pear-shaped composition cayity 2 formed well forward in the nose ,3 of the bullett andhaving its outer end entirely closed so as to give thebulletthe same unbroken exterior contour at the point as ordinary bullets. have, whereby my improved bulletis preventedfrom being fouled in the Specificationcffiettq f Patented Feb. 24, 1135914.

magazine or mechanism of the nn in which it is used. This cavity is partially filled with a charge 5 of any suitable flash-light composition, the character of which may be varied according to well-understood principles to meet predetermined requirements.

Preferably, as I am now advisethl shall employ a flash-light composition: giving a brilliant, intense illumination at the moment of impact with or without a report and with the production of the minimum amount of smoke which will follow the illumination and not obscure it. The composition-cavity O ample charge 5 of flashlight composition as well as an air-space 6 which is located directly between the charge and the apex of 5 the bullet. This air-space may of course be varied in size by varying the size of the cavity 2 and the mass of the charge 5.

In the modified form shown byv Fig. 3 of the drawings, the bullet 7 is formed with a concentric cavity having. a cylindrical rear end S and a conical forward end 9 produced by entirely closing the outer end of the *avity after the introduction of the flashlight co'mposition 10 into its rear end, the cavity being cylindrical throughoutits length as initially formed. The conical forward end 9 of the cavity forms an air-space 11, which is located directly between the flashlightcomposition 10 and the apex of the bullet.

In Fig. l I have shown my invention aplied to a jacketed bullet, the soft-metal core 12 of which is formed at its'forward end with a concentric cylindrical cavity 13 re eeiving a plug-like mass 14 of flash-light composition. In thisconstruction the airspace 15 between the chm osition 11 and the closed apex 16 of the bill et is produced by the hollow point of the jacket 17, whereby the cavity 13 is left of full diameter at. its outer end. i

I claim 1. As a new article of manufacture, an impact-illuminating bullet containing" in its nose a cavity receiving a charge of ilashlight composition, and provided with an airspace located directly between the composi' tion and the apex of the bullet.

2. As a new article of manufacture, an

is made large enough to provide for an impact-illuminating bullet havin a concent -ric cavity receiving a charge 0 flash-light composition, and forming an air-space 'which separates the composition from the 5 closed apex of the bullet.

3. As a new article of manufacture, an impact-illuminating bullet having a closed concentric composition-cavity formed in its .nose and receiving a charge of flash-light composition separated from the closed apex 10 of the bullet by an air ace.

In testimony whereof I have signed this specification in. the presence of two subscribing witnesses. Q:
